This invention relates to numbering transmitters and more particularlyto telegraph transmitters adapted to transmit different multi-digitalnumbers during each cycle of operation.

In the operation of telegraph systems, it often becomes expedient toidentify transmitted messages with a numerical designation preceding thebody of the message. The use of these numerical designations facilitatesthe handling of the message during the routing of each message to itsultimate destination and further the messages identity may be enhancedby merely referring to the numerical designation. Heretofore auxiliarynumbering transmitters have been devised to be used with regularmessagetransmitters wherein coded drums are utilized to close springcontacts associated with each drum whereby electrical circuits arecompleted to cause consecutive multidigit numbers to be generated uponconsecutive operations of the auxiliary transmitter. While thesenumbering transmitters have in general proved satisfactory, they havenecessitated the employment of considerable circuits of pronouncedcomplexity consequently requiring frequent servicing by skilledtechnicians.

It is a primary object of this invention to provide a mechanicallyoperated numbering transmitter.

It is a further object of this invention to provids a numberingtransmitter utilizing coded units for regulating the movement ofmechanical elements to control the generation of signals.

Another object of this invention is the provision of an automatictransmitter employing mechanical instrumentalities for controlling thegeneration of signals representative of functions and multi-digitalnumbers.

Automatic transmitters also iind additional utility in providing meansfor transmitting signals denoting thev readings or settings of clocks,flow meters, wattmeters, or other types of indicators or meters locatedat Various remote stations or installations.

It is, therefore, a further feature of this invention to provide anautomatically controlled transmitter for transmitting signals indicativeof the setting or reading of a clock, meter or indicator.

A more specic object of the invention resides in provision of means forstoring a change in the setting or reading of a clock, meter orindicator during the transmission of signals indicative of the priorsetting of the said clock, meter or indicator.

Wit-h these and other objects in view the present invention contemplatesthe use of a numbering transmitter employing a plurality of sets ofcoded disks having indicia thereon representative of intelligencesignals. Associated with each set of coded disks is a set of followerelements adapted to control the permutative setting of a plurality ofreciprocating selector bars. The permutative setting assumed by theselector bars in response to the permutative setting of the followerelements is utilized to control the generation of permutativeintelligence signals. The first set of coded disks is provided tocontrol the selector bars to assume permutative sets representative ofcontrol functions such as Figures, Letters, etc. whereas the remainderof the sets of coded disks are utilized to control the permutativesetting of the selector bars to assume settings representative ofnumerical digits. Upon completion of transmission of a series of signalsrepresentative of a multi-digital number, means are actuated to causethe coded disks to be advanced to represent the next consecutive number.

In an alternative embodiment of the invention, electrical control meansare provided to be actuated by an extraneoussource of motive power suchas a clock, meter or indicator to cause the sets of coded disks havingnumerical indicia thereon to be advanced in one step increments wherebyconsecutive advancements of the sets of coded disks representconsecutive numbers.

Other objects and advantages of the present invention will be apparentin the following detailed'description when considered in conjunctionwith the accompanying drawings wherein:

Fig. 1 is a side elevational view partially in section showing the codeddisks and the elements controlled thereby embodying the principalfeatures of a numbering transmitter comprising the invention;

Fig. 2 is a top plan view of that portion of the numbering transmittershown in Fig. l, illustrating all of the coded disks and the means forsequentially controlling the transmitter;

Fig. 3 is a side elevational View partially in section showing a signalgenerator controlled by the permutative setting of the selector barsshown in Fig. 1;

Fig. 4 is a side elevational view of an eccentrically operated means forperiodically reciprocating the selector bars; and

Fig. 5 illustrates an alternative embodiment of the' invention whereinthe coded disks are advanced in response to the movement of someextraneous apparatus.

Referring to the drawings and more particularly to Fig. 2, there isshown an electromagnet represented by the reference numeral lll adaptedto control the position of an armature ii pivotally mounted by a stud i2to a bracket, i3 secured to the frame of the apparatus (not shown).Energizing impulses for the electromagnet lil are supplied from anysuitable source such as a special circuit adapted to be actuated by anyof the well known types of telegraph transmitters. Upon energization ofthe electromagnet lll, the armature il is drawn down against theactionof a tension spring lll to engage and move a holding latch l.

Referring now to Fig. l, itl may be seenthat engagement of the armatureil with the holding latch iS pivots the holding latch against thebiasing eilect of a spring il about a pivot shaft I3 until the holdinglatch strikes a stud leattached to a holding bail 2| whereupon the bailpivots aboutl a pivot 22 vthrough the agency'oi tension spring 23attached at one. end to an arm 24 extending from the bail 2i. Bail 2ihas formed on its lower extremity an elongated blade 23 which spans andengages a plurality ofselector bars l-l to 25J. Each of the selectorbars 2li-l to 25-6 are urged toward the right as viewed in Fig. 1 bymeans of extended tension springs 2S individually connected to eachselector bar. The selector har 25J! does not move because it is fixed tosome portion of the frame. It is to be noted that when the stud i9struck the holding latch I6, the stud was positioned in register with arecessed arcuate slot 2l formed in the holding latch I6. Consequentlythe force exerted by the springs 26 through the selector` to 35-5, 36-to Sii-5.314 to 3?5, and 35i-i to 38-5. Each coded disk has formed onits periphery surface certain indicia indicative of an intelligencesignal impulse. ln the present invention as disclosed in the drawings,this indicia takes the form of notches formed in the periphery of thedisk but it is easily within the` providence of any one skilled in theart to provide coded .disks with indicia in the form of projections. onthe coded disks to indicate the, inteligence signal impulses, further itis also within the providence of one skilled in the art to'subestitutecoded drums having. indentationsor pro-v jections formed thereinor thereon in place of the disclosed notched .coded disks.,

In the rest position of the apparatus; as shown in Figs. l and 2, thefollowers 354 to 35-5 are permutatively positioned in accordance withthe v coded indicia on the set of disks Il l to 3l]5. Positioned beneatha notch formed in each free end of 'the L-shaped followers 35-l to.3E-5,7364 to :i5-5, Sli-i to Sil-5, and Sli-l to 33-5 are projectionslll-i to M-E, l2-l to l2-5, l13-1 to 43-5, and vi4-I to ld-5,respectively, formed on the selector bars 2lito 2li-ii. Engaging the l.-shaped follower tti-i to 355-5 is a pivotally mounted holding bail ithaving connected thereto a linkll'l. The link el is connected to aplv-.1

otally mounted follower arm 48 whichisadapted to follow the periphery ofa cam 9 mounted on a sleeve 5S rotatably mounted on a sequence shaft El.In the unoperated position shown in Fig. 1 and 2, the follower t8 ridesupon the high portion of the sequence cam d2 to hold the bail 46 inengagement with the followers 36-1 to 35-5 in such a manner as to holdthese followers YI'ii--i to 36-5 from engagement with the peripheries ofthe coded 'disks Si-l to 3 i-i. In a similar manner, the disk followersBi-l to 3'5-5 are held from engagement with the coded disks 52-5 to.S2-abymeans of a bail S3 having connected thereto a link 543. Again,the link 54 is connected to a follower 55 -which is adapted to follow.the. periphery of a sequence cam 53 mounted on sleeve 5G. in theunoperated positionthe follower lrides upon the high part of thesequence cam iand as a result holds the followersi'i-'l to 31-5 fromengagement with set of coded disks 324 to 32-5. A holding bail 58'1isadapted to engage and hold the l.-shaped followers SS-l to iis-5 fromengagement with the set ofY coded disks B3-I to -33-5. The bail 58 isheld in position through the instrumentality of a link 59 connected to afollower 5l adapted to follow the periphery of a sequence cam G32 fixedto the sleeve 53. In the unoperated position, as shown in l, thefollower SI rides upon the high part of thesequence cam 62 to hold theL-shaped followers .3S-vl to 38-5 from engagernent with the periphery ofthe associated set of coded disks 32-i to 33-5.

Each one of the individual L-shaped cam followers is provided Withasmall individual spring 63 functioning to urge the respective L-shapedfollowers into engagement with the periphery of the associated sets ofcoded'disks. In `the unoperated position of the transmitter as shown inFig. 1 and Fig. 2, the .-L-.shaped followers tti-l to .S5-E are urgedinto engagement with the periphery surface'of the set of coded disksBil-I to 3-5 and the L.-shaped followers 3-5, 355-2, 35-13 and 35-5perceive recesses formed in the coded disks S-, 3(2-2, Sil-l and 31%-5and consequently are pivoted under `the influence of the spring 63 in acounterclockwise direction to bring the notched portions into engagementwith the projections M4, 41-2, dl-il and ll-5 of the selector bars 25-2,25-3, 25-5, andZS-i Thus when the armature ll is drawn down to move thelatch i5, the bail 2| pivots'in a counterclockwise direction to allowthe coded bars 25-i to 25a-B to move towardsthe right'under the inuenceofthe extended. individual spring-s 2t. However, the selector bars 25-2,25-3, 25-5 and 25-5 are prevented from movement by the blocking effectof the notched portions of the followers 354,. 35-2, 354 and 35-5. Theselector bars 25-2 toA 25--8 are .nowpernutatively positioned accordancewith the permutation `of indicia on the set oi"` coded disks Btl-.i to{tit-Ei.

Referring now to Fig. 3, there is shown a signal generator of the samegeneral type shown and described in great detail in the copendingapplication of W. J. Zenner entitled Telegraph Keyboard Transmitter,Serial Number 95,964 led May 28, 1949 now U. S. Patent No. 2,607,843dated August 19, 1952. The description and disclosure contained in thiscopending application is hereby incorporated by refer-ence into thepresent description. Theselector bar 25-l is uti-- lized to'initiateoperation of the signal generator and has'formed inY its left vextremitya notch te into which is positioned a clutch release latch lever 57. Arelativelyweak'ispring 16B in corn- Figs. l, 2 and 3 to pivot the clutchrelease latch1 lever 61 in a counterclockwise direction to withdraw anotched portion 69 from engagement with Y a clutch 1I which may be of afriction disctype, j

well known in the telegraph art, or of the type shown in the patent toA. N. Nilson et al. No;

2,568,249 dated september v18. 1951. The only requirement of this clutch1| being the ability to be instantaneously engaged upon actuation of theclutch release latch lever 61 and that it be disengaged upon movement ofthe clutch release latch lever 61 to the initial position.

Each of the selector bars 25| to 2.5-1 is also provided on its upperedge with a notch 12 (Fig.

3) which cooperates with the lower extremity:

of a transfer lever 13.

Levers 13 are pivotally mounted on a suitably supported pivot rod 14 andare urged in a counterclockwise direction by individual springs 16. Inthe unoperated position, the transfer levers 13 are normally held-`against the action of the spring 16 by the right walls of the notches 12formed in the selector ,Y

bars `25-I to 25-1 and when the selector bars are permitted to moverightwardly the associ' ated transfer levers 13 are permitted to rotatecounterclockwise a predetermined amount under the action of theindividual springs 16. Pivotally articulated within an arcuate slot 11formed in the upper portion of each trans-4 fer lever 13 is aninterponent member 18. Each transfer lever 13 and associated interponentare maintained in cooperative relationship by the particular connectionbetween these elements which is a circular section formed on each infvterponent member 18 fitted within the arcuate slot formed in eachtransfer lever 13. A tension spring 8| is connected to each free end ofthe interponent members 18 to urge said interponent members intoengagement with a pair of spaced guide rods 82 and 83. Each interponentmember 'i3 is adapted to cooperate with an individual cam 64 fixed to apower shaft 86. Only one cam 84 is shown but it is to be understood thatsix other identically shaped cams are also mountf ed on the power shaft86. Formed on each interponent member 'I8 is a pair of marking andspacing abutments 81 and 88, respectively, adapted to cooperate underpredetermined conditions with a pair of depending flanges 9| and 92,respectively, of a rocker member 93 pivotally mounted on a pivot shaft94. Rocker member 93 is formed to provide an upstanding arm'gefi havinga pin 91 secured to its upper extremity.' Pin S1 is positioned withinbifurcations forming part of a contact-rocker 98 pivotally mounted on arod 99. Contact rocker member 99 has a pair of laterally extending armsI| and |02 adapted to carry contact elements |03 and |04 into engagementwith transmitting contacts and i 01, respectively.

Cams 84, seven of which are provided in the present embodiment of theinvention, have D130- iections formed thereon which are arranged heli;cally so that upon rotation of the power shaft 86 the cams are rotatedto successively present their projecting portions to the interponentmem; bers 18 wherebythe interponents are successively oscillated. Thusif the selector bars -2 to 25-6 are not permitted to move rightwardlybecause the projections formed thereon are engaged by the L-shap-edfollowers of one set of coded disks then the associated interponents 18will remain in the positions shown in Fig. 3 with the abutments l81 inalignment with the flange 9| of the rocker member 93. Therefore, whenthe cams 84 are rotated, the interponents are oscillated upwardly tobring the abutments 81 into engagement with the flange 9|, to rotate therocker member 96 in a clockwise direction if the rocker member 96 hasnot already been positioned in its clockwise position. On the otherhand, if the selector bars 25-2 to 25-6 are permitted to moverightwardly then the associated interponents will be moved towards theleft by the transfer levers 13 to bring the abutments 88 into alignmentwith the ange 92 of the rocker member 93. There-` fore, when the cams 84are rotated, the interponents 18 associated therewith will be oscillatedto bring the abutments 88 into engagement with the flange 92 to rotatethe rocker member in a counterclockwise direction.

It may be therefore appreciated that when the selector bars 25-2 to 25-6assume a permutative f setting in accordance with the coded indicia onany one of the sets of coded disks this permutative setting istransferred through the instrumentality of the transfer levers 13 to theinterponents 18. Consequently, when the interponents 18 assume apermutative position, then the subsequent rotation of the earns 84successively bring either abutment 81 or 88 into engagement with therespective flanges 9| and 92 to successively rotate the rocker member 96in a clockwise or counterclockwise direction in accordance with thepermutative setting of the interponents 18. Upon the interponents 18assuming a permutative position, a cam III pivots a locking lever ||2 ina clockwise direction to bring a locking bar I I3, formed integraltherewith, into position to engage with the left or right side ofpointed ends |I4 of the transfer levers 13. depending upon thepermutative setting of the transfer levers 13. The function of thelocking bar ||3 is to hold the permutative setting of the transferlevers during the successive operation of the cams 84, even though theselector bars 25-I to 25-6 may be returned to the initial positionbefore the operation of all of the cams In the embodiment of theinvention herein described contacts 04 and |01 function as marking orcurrent contacts and the contacts |83 and |06 function as no current orspacing contacts. It is to be understood that the contacts |06 and |01are connected within the transmission circuit of any telegraph system.Therefore, closing of either of these contacts applies to either a'marking or spacing condition to the transmission. circuit. Although theinvention is described wherein the contacts are either connected tobat--v tery or not to battery, it is to be understood that the contact|01 could be connected to positive battery and the contact |86 could beconnected to negative battery to cause the operation of a polartelegraph transmission circuit.

There is mounted on the power shaft 86 an eccentric I|6 (see Fig. 4)positioned within a yoke I I1 of an arm I I8 having a hook I I9 formed 3on its right end. The arm I I3 is adapted to pass through an aperture|2| formed in the holding bail 2|. The eccentric |16 is adapted to movethe arm I|8 towards the left subsequent to the engagement of the lockingbar I|3 with the Z pointed ends I I of the transfer levers 13. Move#vvacc/'7,013

ment of Ythe arm ||8 towards the left moves the hoo-k ||S intoengagement with the bail 2i to move the bail 2| in a clockwise directionto move all of the selector bars 25| tov 25-6 towards the left and henceto the initial position. The eccentric I |6 functions to hold theselector bars in the initial position until such time as the cams 8shave all functioned to oscillate their respective interponent members i8whereupon the eccen tric H6 functions to move the arm H8 towards theright and as a result the bail 2| is moved in a co-untercloclrwisedirection. Movement of the bail 2i in the counterclockwise directionagain permits the individual selector oars 22S-i to 251-5 to :novetowards the right under the iniiuence of the extended tension springs itand thus assume another permutative setting in accordance with thepermutative indicia of a set of coded disks.

v Returning now to Fig. l, there is shown a link `|22 connected at oneend to the bail 2i and at its other end to valever |23. The lever i523is pivotally mounted about the sequence shaft di and haspivotallymounted on :tree end a feed pawl |2fil adapted to cooperate with theteeth of a ratchet .i fixed to the sleeve 552. A spring |21 engages andbiases thepawl 52d into engagement with the teeth of the ratchet |25.Manifestly, each time the bail 2| is oscillated by the eccentric ||'Gthe feed pavvl 25, advances the ratchet |26 and as, a consequence all ofthe cams 49, 55, 62 and the coded dist lit-i to Sii-i5 are advancedoneAincrement. Also mounted on sleeve G and secured thereto is a locking camadapted to control the position ci' a V-shaped locking member |29.` Whenthe locking cam is advanced, one increment by the pawl and ratchet |25,the locking member E is moved from a low portion or" the cam it to ahigh portion thereby pivoting the locking member itil in acounter-clockwise direction and into engagement with an extending tip|3| of the holding latch it. The holding latch l5 is thereby held in anunlatched position during the period in which the locking member |2Sengages the tip u |3| thereby permitting subsequent oscillation of thebail |2 by the eccentric H5.

In operation of the numbering transmitter, an energizing impulse isreceived by the electromagnet |t to cause the electro-magnet to drawdown its armature to engage and move the holding latch it fromengagement with the stud iii. Released, the stud i9 permits the bail 2|to move in a counterclocltwise direction under the iniluence of itsspring 23vvhereupon the selector bars 25| to 2li-ii are moved towardsthe right as viewed in Fig. l under the influence oi extended springs2t. The L-shaped followers .t5-l to 3.5-5 are permutatively positionedin accordance with the coded indicia on the coded disks 3i| to .td-. Asshown in the present embodiment of the invention the coded disks SEA,-2, 3Q-Li and tE-5 have indentations formed therein. Consequently thefollowers S-I, 35,-", 35-4 and 35-5 pivot in a oounterclcckwisedirection under the iniiuence of the springs 53 to bring the notchedportion into engagement with the projections i||, ii-, i-G and lil-5formed on the selector bars 25-2, 25-3, 25-5 and 25-6 to prevent thesecoded bars from moving towards the right. The permutative setting of theselector bars 254 to 25-'1 is imparted to the transfer levers 'i3 tolpermutatively position the interponents 18. rhe selector bar 25| has noprojections formed thereon and as a: consequence invariably moves towardthe fifi right upon each counterclockwise movement of the bail 2|.-Movement of the selector bar 25| not only positions` its associatedtransfer lever but also pivots the clutch release lever 'El in acounterclockwise direction to remove the notched portion 69 from theclutch 7|. Release of the clutch 7| instantaneously allows power from asuitable source such as an electric motor to be imparted to the camshaft 86. Rotation of the cam shaft 86 causes rotation of the camsmounted thereon and hence the high portions of the cams all aresuccessively presented to the permutatively positioned interponents 18to successively move the abutments 61 or 88 into engagement with thealigned iianges 9| or 92. It may be therefore readily appreciated thatthe rocker member 93 is successively positioned in accordance With themovement of either the abutment 8i or the abutment 88 into engagementwith the respective flanges 9| or 52. Movement oi the rocker member 93is imparted to a contact rocker e8 to control the making or breaking ofcontacts libri and |21 or the contacts |03 and i135. Thus, the contactsare successively closed in accordance with the permutative setting ofthe selector bars 25-5 to 25e-l. This setting is representative of aFigures .signal in accordance with the Baudet code and as a consequencea Figures signal is imparted to the transmission circuit.

selector bar '2E- is fixed to hold its translever and interponent invsuch a position that the abutment 2 is maintained in alignment with thesi. Consequently, in each series of rotation of the cams B, the abutment8l on the interponent 'it associated with the selector bar .Q5-i ismoved into engagement with the ange Si to cause the contacts it and imto close to impart a marking condition to the transmitting circuit. Inuse of `the Baudot code, in telegraph apparatus, each intelligencesignal comprises a spacing or no current impulse followed by a series ofpermutative impulses andthen by a stop current or marking signal. It maybe therefore understood that the selector bar 25-'5 is utilized toprovide a stop impulse for eachintelligence signal transmitted bytheapparatus. This is accomplished by having the cam which actuates theinterponent 'i8 associated Vwith the selector bar ziifunctioningsubsequent to the transmission of each permutative series of impulses.

The start impulse for each series of signals is provided by having theselector bar 25| move towards the right each time the bail 2| is moved iin a counterclockwise direction. As previously indicated, movement ofthe selector bar 2| towards the right permits the movement of thetransfer lever 13 in a counterclockwise direction to move theinterponent 18 to such an extent as to position the abutment B8 inalignment with the flange The .cam '34 associated with the selector bar25-I moves its` lobed portion into engagement with its interponents I8immediately following the permutative setting of the interponent i8 andas a consequence the abutment 88 is moved into engagement withthe ange92 to cause the `contact |i`z3 to move into engagement with the Contacti536 to impart a spacing or no current impulse to the transmittingcircuit. This spacing or no current impulse is utilized as a startimpulse and is imparted to the transmitting circuit prior to thepermutative intelligence impulses.

As soon as the, transfer levers 13 are locked in position by the lockingbar I3,v the eccentric moves the arm ||8 and bail 2| towards the lefttoreturn all of the selector bars to 25-6 to the initial position.Movement of the bail also moves the link |22 and the lever |23 to engagethe pawl |24 with a tooth of a ratchet |26 to advance the ratchet andall of the cams mounted on the sequence sleeve 50. Followers 35-I, 35-2,35-4 and 35- 5 are moved from within the recesses in the coded disks -l,30-2, 311-4 and 3D-5 to high portions of the coded disks. Therefore, allof the followers to 3-5-5 are positioned on high portions of the disks3Il| to 39-5 and as a result their trailing arms are no longer inposition to block any of the selector bars 25-2 to 25-6. Simultaneously,the follower 6| falls within a notch formed in the sequence cam E2 tomove the link 59 towards the left and hence remove the bail 58 fromengagement with the followers 38| to 38-5. The followers 38| to 38-5 areimmediately permutatively positioned in accordance with the codedindicia on the; coded disks 33| to 33-5. The eccentric I6 now functionsto release bail 2| and hence the coded bars 25-2 to 25-6 arepermutatively blocked in accordance with the followers 38| to 38-5 beingpermutatively positioned within the coded recesses in the coded disks33-I to 33-5. Movement of the selector bar 25| which occurs upon everyrelease of the bail 2| again causes the clutch release lever to pivot toallow the clutch 1| to remain engaged. Upon completion of transmissionof the first complete intelligence signal, the locking bar I3 is removedfrom engagement with the pins ||4 and the interponents 13 arepermutatively positioned in accordance with the permutative positionsassumed by the selector bars 25| to 25-1 and another intelligence signalis thereupon transmitted by the single generator shown in Fig. 3.

Upon completion of the transmission of the second signal which isindicative of a hundreds digit,v the sequence cam 56 is renderedeffective to move the bail 53 from the followers 37| to 31-5 and as aresult the followers are permutatively positioned in accordance with thecoded indicia on the coded disks 32| to 352-5. The coded indicia on thecoded disks 32| to 32-'5 is indicative of the tens 'digit of amulti-digit number. Movement of the follows 31| to 31,-5 into thepermutative position controls the permutative setting of the selectorbars 25-2 to 25-6 and as previously discussed this permutative settingof the selector bars is utilized to control the genera` tion of anintelligence signal by theY signal generator shown in Fig. 3.

Upon completion of the transmission of the intelligence signalrepresentative of the tens digit, the sequence cam. 49 is renderedeifective to remove the bail 46 from engagement with the followers 36|to 36-5 and as a result these followers are permutatively positioned inaccordance with the coded indicia on the vcoded disks 3| -I to 3|-5. Thecoded indicia on the coded disks 3 to 3 |-5 is representative of unitsdigit. Therefore, the followers 36| to 36-5 are permutatively positionedto control the permutative setting of the selector bars 25-2 to 25-5.tion assumed by the selector bars 25| to 2'5--7v controls the signalgenerator shown in Fig. 3 to cause the generation of a signalrepresentative of a units digit.

Following the transmission of all of the digits of the multi-digitnumber, the coded disks 3| to 3U-5 are again advanced and renderedeffective to control the permutative setting of the selector bars 2.5-2to V256. However, the intelli-` The permutative posigence signal now tobe transmitted is a Letters signal which according to the Baudot codehas ve marking impulses. In order to obtain this signal, all of thefollowers Z55-l to 35-5 are moved into blocking position and as a resultall of the selector bars 25-2 to 25-8 are held against movement towardsthe right to cause the signal generator shown in Fig. 3 to generate aspacing start signal followed by ve marking intelligence impulses andthen by a marking stop signal impulse.

It is to be noted that for the complete transmission of a three digitnumber five signals are transmitted, hence the ratchet |25 is advancedfive increments for each complete cycle of operation of the transmitter.The ratchets and the cams are so arranged that ve advancements of theratchet cause the coded disks 3D| to 30-5 and sequence cams 49, 5S and6| to rotate through The coded disks 21d-l to 30-5 and sequence cams areso marked or cut that each mark or cut repeats in every quadrant of therespective elements mounted on sleeve 50. Upon the cam |23 advancing iveincrements a second recess portion is presented to the locking member|29 causing said locking member to pivot in a clockwise direction torelease the tip |3| of the holding latch It whereupon the stud I9 of thebail 2| engages the holding latch I6 to prevent further oscillation ofthe bail 2|. In this condition of the apparatus, the selector bar 25| ispositioned in its leftwardly position causing the clutch release lever|57 to pivot thereby moving the notched portion GQ into engagement withthe clutch H to prevent further rotation of the power shaft S6 and tohalt the transmission of any further intelligence signals.

Positioned on the sequence sleeve 50 and adapted to rotate therewith isan additional cam |33 which functions upon completion of transmission ofeach multi-digit number to pivot a follower |34. Connected to the upperextremity of the follower |34 is apawl |36 vspring biased intoengagement with the teeth of a ratchet |3 xed to a, shaft |38. Shaft |38provides a mounting for the coded disks lilto SI-S, and as a result,movement of the follower |34 is impartedy through the pawl |36 to theratchet |31 to ad- Vance all of the coded disks ii-l to 3|-5 a distanceof one tooth or 18. The coded disks 3|| to 3|-5 have two series of codedindicia thereon representative of the digits 0 to 9. Movement of thecoded disks 3|i to 3|-5 through 180 positions the second series ofcodedindicia representative ofthe digits O to 9 to control thepermutative setting of the followers Sii-I to 36-5. Mounted on the shaft|38 is a cam |39 adapted to control the position of a follower |40. Thefollower |40 is pivotally' mounted and has pivotally mounted on oneextremity thereof a spring biased pawl |42 adapted to cooperate with theteeth of a ratchet |43 fixed to a shaft |44. The coded disks 324| to32-5 are fixed to the shaft IM, thus movement of the'ratchet |43 by thepawl |42 advancesthe coded disks 32-i to 32-5 one increment. Again thecoded disks 32| to 32-5 have two series of consecutive coded indiciathereon representative of the digits 0 to `9.

Fixed to the shaft |44 is a cam |46 having two lobes spaced apart.Adapted to follow the cam |46 is a follower |41 having pivotally se-`cured to one extremity thereof a pawl |48 which cooperates withandfa-dvan'ces the teeth of a ratchet |49. The ratchet |49 isiixed to` ashaft |5| whichalso carries-the coded disks 33`| toV 11 33-5. The codeddisks 33-| to 33-5 have two series of coded indicia formed thereonindicative of the digits to 9.

Accordingly, it becomes apparent that upon completion of eachtransmission of a multi-digit number, the coded disks 3|| to 3|-5 areadvanced one increment to present the indicia representative of the nextconsecutive numerical digit to the followers 36| to 36-5. Upon each tenadvances of the coded disks 3|| to 3|-5, one of the lobes on the cam |39is rendered effective to actuate the pawl |42 and ratchet |43 to advancethe coded disks 32| to 32-5 one increment to present the indiciarepresentative of the next consecutive numerical digit to the followers31| to 31-5. When the coded disks 32| to 32-5 are advanced tenincrements, one of the lobed portions of the cam |46 is ren-deredeffective to actuate the pawl |43 and ratchet |49 to advance the codeddisks 33| to 33-5 one increment whereby the indicia representative ofthe next consecutive numerical digit is positioned to control thefollowers 38| to 38-5.

In reviewing the operation of the numbering transmitter, it may bereadily appreciated that the following sequence of signals aretransmitted: first, a Figures signal under the control of the codeddisks 30`| to 3-5, second, a hundreds digit number under the control ofthe coded disks 33| to Sii-5, third, a tens digit under the control ofthe coded disks `32| to S22-5, fourth, a units digit under the controlof the coded disks 3|l to `2l-L1 and nally a Letters signal under thecontrol of the coded disks Bil-l to 3|l-5.

Referring to Fig. 5, there is shown an alternative embodiment of theinvention for use in systems wherein it is desired to automaticallytransmit signals representative of the setting of a clock, meter orindicator. The apparatus shown in Fig. 5 is in many ways identical tothe apparatus shown in Figs. 1 to 4 and where such parts are the same inthe Vtwo embodiments, identical numerical designations of the respectiveparts are used. A solenoid controlled armature controls the position ofa latch |6 which upon release permits a bail 2| to oscillate through theinstrumen-- talitylof the mechanism shown in Fig. 4. Therlatch I6 islocked in position through the'inst'rumentality of a locking member |29when said locking member rides upon -the high part vof the cam |28. Aspreviously described in regard to the first embodiment of the inventionthe selector bars 25-2 to 25-6 are adapted to be permutativelyYpositioned in a successive' manner by sets of coded diskA followers 35-lto 35-5, IE6-l to |56-5, |51| to ll-5, |58| to |58-5, |59| to IES-5 andfinally againby the followers 35| to 35-5.

In the embodiment shown in Fig. 5, the method of advancing the codeddisks is not under the control of a cam on the shaft 5| but rather froman independent source which is underthe'control of a clock designatedgenerally by the 'reference numeral |60. In Ythis instance, thereference numeral ISI designates a cam which is rotated once everyminute by the clock '|60 lto close a contact' |62. Closure of thecontact |62 completes a cir'- cuit from positive battery,l through thecontact |62, overa lead |53, through asolenoid n|64, overr a lead |66',to negative battery. Energiz'ation of the solenoid |64 draws up itsarmature |61 which is 'pivotally connected to a lever |68. Pivotallyconnected at they midpoint of the lever |68 is a spring biased'pawl |69urged into engagement with the teeth of a ratchetf|1| mounted on a shaft|12. Also moutedon thesh'a'ft |12 is ya set of coded disks |13| to |13-5having coded indicia thereon representative of two series of digits 0 to9. In addition, a two lcbed cam |14 is xed to the shaft |12 and for eachten increments of advance of the ratchet |1|, a lobe is brought intoengagement with a follower |16 to pivot the follower. Pivotallyconnected to the free end of the follower |16 is a spring biased pawl|11 adapted to engage and advance the teeth of a ratchet |18 fixed to ashaft H9. Secured to the shaft |19 is a set of coded disks |8|| to |8|5having three series of indicia representative of the digits 0 to 6. Inaddition there is secured Ato the shaft |19, a cam |32 having threelobes spaced apart to separate each series of coded indicia.

A follower arm |83 is adapted to follow the periphery of the cam |82 andupon encountering a lobe is moved to advance a spring biased pawl |84into engagement with the teeth of a ratchet |86. The ratchet |86 issecured to a shaft |81 which has securely fastened thereto a set ofcoded disks |88| to IBB-5. The coded disks IBS-I to ISB-5 have twoseries of coded indicia thereon representative of the digits (l to 9.Fixed to the shaft |81 is a cam |9| having two lobes thereon spacedapart to separate each series of coded indicia.

When the cam |9| advances ten increments, a lobe on the cam is broughtinto position to move a cam follower |92 in a clockwise direction. Themovement of the follower |92 is imparted to a spring biased pawl |93 toadvance a ratchet |96 xed to a shaft |98. Secured to the shaft |95 is aset of coded disks |91-I to |91-5 having two series of coded indiciathereon each representative of the digits 0 to 9.l

Associated respectively with each set of followers |5S| to IE6-5, |51|to |51-5, |584 to |585, and |59| to |59-5 are a series of hails 20|,262, 283, and 264, adapted to be controlled respectively by the links296, 261, 28, and 269. Each of the links are connected to separate camfollowers only one of which is shown in Fig, 5 and designated by thereference numeral 2| l. However, it is to be understood that additionalfollowers are provided to be connected to the other links. Eachfollower, such as follower 2| is adapted to follow the periphery of asequence cam mounted on the shaft 5|, only one of which is shown and isdesignated by the reference numeral 2 l2.

In operation of this embodiment of the invention, the armature is againmoved downwardly to release the holding latch It to set transmitter inoperation. The selector bars 25-2 to 25-6 are permutatively positionedin accordance with the permutative setting of the L- shaped followers35| to 35-5. The permutative setting of the selector bars is utilized tocontrol the actuation of the signal generator shown in Fig. 3 in'anidentical manner with that described in regard to the rembodiment of theinvention shown in Figs. l, 2, 3, and 4.

Upon completion of transmission of the first intelligence'signal, thebail 20| associated with the followers |56| to 156-5 is released toallow these followers to assume a permutative position in accordancewith the indicia on the coded disks |91| to |91-5 and hence control theperstting'in accordance with the coded indicia on the coded disks ISB-Ito IBS- and hence control the permutative setting of the selector bars25-2 to 25-6 to control the signal generator shown in Fig. 3. The nextoscillation of the bail 2| withdraws the ball 293 to permit thefollowers |58| to |58-5 to assume a permutative setting in accordancewith the coded indicia on the coded disks |8|| to IBI-5 and thus controlthe permutative position of the selector bars 25-2 to 25-6 to cause thesignal generator shown in Fig. 3 to generate a signal indicativeof thecoded indicia on the coded disk. The nextoscillation of the bail 2|effectuates a withdrawal of the bail 205 to permit the followers |59| toI 59-5 to assume a permutative setting in accordance with the codedindicia on the coded disks |`|3| to |13-5. The next oscillation of thebail 2| again positions the followers 35| to 36-5 in accordance with thecoded indicia on the coded disks 39| to 30-5 and as previously indicatedall of the followers are moved into blocking position to prevent all ofthe coded bars 25-2 to 25-6- from moving towards the right toI controlthe signal generator shown in Fig. 3 to produce a signal indicative of aLetters function. Upon. completion of the transmission of vthe Letterssignal the. blocking member |29 is moved into position to permit thelatch |6 to move upward to engage the stud I9 on the bail 2| andmanifestly the apparatus then comes to rest.

`An additional feature of this particular ern` bodiment resides in ameans for storing changes in indications of the clock actuated cam |6|.If during the course of a transmission cycle, the cam |6| closes thecontact |62, then the circuit is completed from positive battery throughthe now closed contact |62, over the lead |63, through the solenoid |64,over the lead |66 to negative battery as previously described.Energization of the solenoid |64 draws up its armature |61 to move thelever |68 and the pawl |69 in a counterclockwise direction. Thismovement of the pawl |69 causes a leftwardly extending portion 2|@thereof to engage and closer a contact 2M. When the transmitter is inthe process of transmitting signals representative of the coded'indiciaon the various coded disks the blocking member |29 is pivoted in acounterclockwise di` rection to close a contact 2|6. contacts 2|4 and2|6 completes a holding circuit for the solenoid |64 which may be tracedfrom Closure of .the

positive battery over a lead 2|1, through the solenoid |64, thus thepawl |69 is advancedin a clockwise direction to advance the ratchet il!one increment to indicate the rotation of the clock actuated cam |6|during the previous transmission cycle.

A rsum of the operation of theembodiment of the invention shown in Fig.5 reveals that this transmitter causes the transmission of a two digitnumber indicative of hours and a two digit number indicative of minutes.When the coded disks. |8|| to ISI-5 are advanced six increments toindicate-'a 60 minute passage ofy time' the next series of coded disks|88| to Hi8-5 are advanced one increment to indicate an additional hourin passage of time. It is to be understood by those skilled in the artthat other means besides a clock could be utilized to actuate the cam|6|. These devices could possibly take the form of a wattmeter or a flowmeter or a gas meter or any other instrument used to measure a quantity.
